The main problem is reservation of hotels. I phoned several yesterday, the youth hostels are already nearly fully booked (they have some doubles left, but not enough for all of us...) and they will not take a reservation without secure booking and advanced payment. So I think the best would be that everybody does his own booking via HRS ( http://www.hrs.de/ ) (and search for an accommodation close to the main station...)

btw and going a bit off topic:
German beer is highly diverse and an important part of Germany's culture. There are around 1,300 breweries in Germany. The German beer market is sheltered from the rest of the world beer market by the German brewers' adherence to the Bavarian Reinheitsgebot (purity requirement) dating from 1516, according to which the only allowed ingredients of beer are water, hops and barley-malt. Because of this law beers from Germany have a reputation for high quality. There is a variety of different types of German beer, such as Kölsch, a pale, light-bodied, beer which can only legally be brewed in the Cologne region.

On the other hand in Belgium there are approximately 125 breweries in the country, producing about 500 standard beers. Which is quite a number for such a small country.

When trying to find something about dutch beer I can only quote Wikipedia:

"The beer culture in Netherlands is a bit different from, for example, Belgium and Germany. Beer is regarded as either a delicacy or just a way to get drunk, the latter being predominant among youngsters who are allowed to consume alcohol from age 16."

Maybe that is the reason for only four main brewery companies in the Netherlands...

(Sorry about the size and quality ,somehow I managed to delete the pics from the computer , so I had to copy the pics from my facebook album.Facebook reduced them in size and quality of sharpness (which I did not realise ).But still I think they show how much fun we had )
